Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of active pharmaceutical ingredients (APIs) that require nitrogen-containing heterocyclic structures. It serves as a building block in the development of drugs targeting central nervous system disorders and metabolic diseases. Its structure allows for functionalization at multiple sites, making it valuable in medicinal chemistry for creating diverse compound libraries during drug discovery. Also utilized in the preparation of agrochemicals and specialty chemicals where cyclic amide derivatives are needed.
